G'day All, Well here is something a little different and really just a bit of fun. Over Christmas, I picked up an EPP Eagle on sale from Banggood. I ordered the Eagle along with their recommended motor and ESC, but I had a message from Banggood to tell me they are out of stock of the ESC, but I could select an alternative. So, being too keen to wait, I made a selection and the gear arrived a week or so after.
Here is the build and the failed maiden.
The suggested CG of 70mm in the instructions is completely wrong, way too far back.
I got mine here -

Switched to this one - https://goo.gl/9WcFjW
Racerstar BR2212 1000kv Motor - https://goo.gl/h70Ru4
MG90S Metal Gear Sevro - https://goo.gl/xu4WbZ
EPP Mini Eagle - https://goo.gl/I9s6M6
The nose section has been reinforced now and it will fly again. Maybe tomorrow, probably the next day.
Cheers
Michael
I agree with EC White. I also added downtrust (3 washers) and moved battery
(3S 1800 MaH) just behind the motor. Flies like a bird now
"I maidened mine yesterday. 40mm CG, thin ply all the way to mtr mount, 1400KV
motor, right and down thrust, flew right out of my hand. I couldn't tell which
way was fwd on the ply sides. I think the way with the servos more rearward
would be best as a 2200 3s could be placed farther back, but the 1500 3s is fine
at about 1"" in front of the servos with esc up front and rx in back. I had to
cut some small cooling holes on the bottom front and rear as well. Here is a
link to my 2nd flite-I was surrounded by a bunch of hawks! Then when I was
landing, as I cut power the tail feathers lost authority and it hit my legs. I
was glad I had the ply in the nose!

I had to add down thrust to the motor and move the battery forward to get mine
flying correctly.
Mine had 2 issues, first moving the battery forward corrected the
glide/power-off flight. However with just about any amount of throttle it
climbed like it was tail heavy. Down thrust on the motor fixed that. BTW, last
summer I was flying several hundred feet up, when a hawk attacked and actually
hit it. That was really cool to see.

Maybe a way to avoid drone regulation..?
Michael you will need 2-3mm of reflex with a v tail at 90 deg this model is
essentialy a flying wing good luck
